squeak on the ps3
by Gary Frederick 09 Jan '07

09 Jan '07

Howdy I am interested in squeak on the sony ps3. I think it would be a great platform for education. The ps3 comes with Linux and is reported to support other operating systems (SQUEAK OS?). It has state of the art multimedia hardware. Yellow Dog Linux has already announced their Linux will be available on the ps3. The various coprocessors and other hardware would be a lot of fun with plugins. Squeak on a HD 1080p display!!! I think the ps3 could attract lots of kids that want to build media. We plan to play with a squeak wiki and croquette on the assumption that they would be great collaboration tools for working with kids and education. Etc etc enthuse enthuse ;-) If they sell the million consoles the first year... hmmm Is anyone else interested in a ps3 squeak? Gary

The Weekly Squeak Summary No. 8: Nov 19, 2006 - Jan 6, 2007
by Michael Haupt 08 Jan '07

08 Jan '07

Dear Squeakers, welcome to the The WeeklySqueakSummary, a weekly report on what's going on in the world of Squeak based on the WeeklySqueak blog. Merry Christmas and a happy new year! It's been quite a while since the last summary, for various reasons. Several low-traffic weeks didn't make summarising them look sensible, and then there were the holidays... here we are again. Highlights of the past weeks: The OLPC project is still being (sometimes heatedly) debated. Nicholas Negroponte, the project's founder, pointedly discusses the project opponents' opinions in a video [1] that also contains some educators' comments. Another video contains a talk on Exupery by Bryce Kampjes [11]. The slides are readable in the video, but unfortunately, the video itself is incomplete because the tape ran out during recording. Finally, there is a tutorial on setting up a SqueakSource image to create your own SqueakSource server [9], making available project-oriented version control for everyone without the need for having access to the server at squeaksource.com itself. The past weeks' news items: [1] Extra! Gemstone Goes Seaside! http://weeklysqueak.wordpress.com/2006/11/21/extra-gemstone-goes-seaside/ [2] Touring Seaside.

Squeak speed under Mac OS X
by Steve Moffitt 06 Jan '07

Aleksander -- You might try using the 3.7-7 Unix VM for your image which you can download from http://squeakvm.org/unix/ . I have found some of the newer vm's can really slow down the system especially if you are using some of the true type fonts. Yet another Steve

Without DejaVu fonts GUI works much better, but it still seems to be very heavy for my machine (for example, scrolling of the "Changes that have been done in 3.9" window gives 100% CPU load).

Disabling halos and the world menu
by Jens Pall 05 Jan '07

05 Jan '07

Hi How can I prevent the halos from appearing when clicking the middle mouse button? I tried Preferences>>disableProgrammerFacilities but the halos still appear. The World menu (left mouse button) also still appears. Shouldn't this command also disable it? I'm interested in locking the image down as much as possible in order to be able to ship it running a product sold by my company. I'm using VM 3.7.1 on Windows and image 3.9-final-7067. Thanks, JP

Subject: [Newbies] Creating a Form Editor
by Aleksej 05 Jan '07

05 Jan '07

Hello! > (Form new extent: 300 @ 400) edit" > It didn't work for me in Squeak 3.8 (on my Macintosh). In system browser you can open class Form and in editing category along with #edit there is #morphEdit method. It is work in Morphic. At least on my computer this work: (Form extent: 200@200 depth: 8) morphEdit Good luck. Alexej.

Creating a Form Editor
by Bruce Prior 05 Jan '07

05 Jan '07

Hi Squeakers, I have been reading Adele Goldberg's classic text, "Smalltalk-80 The Interactive Programming Environment," and came across this in Chapter 7, "How to make Pictures." Adele states, "Create a Form Editor by evaluating an expression of the form, (Form new extent: 300 @ 400) edit" It didn't work for me in Squeak 3.8 (on my Macintosh). Further down, Adele says, "The message edit can be sent to any instance of Form." But when I checked with my browser I found that Form has a class method extent: but not an instance method extent:. So I tried (Form extent: 300 @ 400) edit and the Form Editor appeared as desired. Is this because Smalltalk and Squeak are different somehow, or is there a mistake in the text, or? If the text is correct, then I still don't fully appreciate the difference between class and instance methods. Bruce Prior (still looking for "ah - ha!" and I think it's close....)

Thanks, Aleksandr P.S. Sorry, if I've duplicated this message, but it seems that my previous post was deleted, for I was not registered.
